abstract = {In electron cryomicroscopy (cryo-EM), molecular images of
vitrified biological samples are obtained by conventional
transmission microscopy (CTEM) using large underfocuses and
subsequently computationally combined into a high-resolution
three-dimensional structure. Here, we apply scanning
transmission electron microscopy (STEM) using the integrated
differential phase contrast mode also known as iDPC–STEM
to two cryo-EM test specimens, keyhole limpet hemocyanin
(KLH) and tobacco mosaic virus (TMV). The micrographs show
complete contrast transfer to high resolution and enable the
cryo-EM structure determination for KLH at 6.5 Å
resolution, as well as for TMV at 3.5 Å resolution using
single-particle reconstruction methods, which share
identical features with maps obtained by CTEM of a
previously acquired same-sized TMV data set. These data show
that STEM imaging in general, and in particular the
iDPC–STEM approach, can be applied to vitrified
single-particle specimens to determine near-atomic
resolution cryo-EM structures of biological macromolecules.},
